To all whom it may concern:

Be it known that ARTHUR STUART GIL- BERT, a subject of the Kin residing at Soho F oun England, have invented ry Birmingham a riewfiand useful Improvement in ResidueWeighers; and he does hereby declare the following to be a full, clear, and exact description of the same.

1 This invention has reference to improvements in residue weighers employed in conjunction with automatic weighing scales and refers particularly to residue weighers of the kind described in the United States Fat cut No. 1,233,641 wherein a record of the residue may be obtained. In the aforesaid prior specification the graduations upon, the steelyard were arranged in what is normally a reverse direction to that in common practice in connexion with ordinary weighing steelyards, and it has been found that in certain instances this reversal of the order of the graduation has led to confusion'or mitigated against the rapidity of operation or adaptation of the residue wei her.

The present invention obviates this disad vantage by employing a steelyard wherein the graduations upon the steelyard are arranged in the opposite directions to those of the aforesaid apparatus, that is in the ordinary mannen of a weighing steelyard, the zero graduation being nearest to the-fulcrum of the steelyard. 1

The invention comprises a residue weigher of the kind wherein the record is obtained from a steelyard and adjustable poise wei ht mechanism, said steelyard being gra uated from the fulcrum of the steelyard, the steelyard being overbalanced in itself or by means of weights connected thereto by levers or linkage.

The invention is capable of being carried into effect in different ways but for the purpose of the present specification one means will beparticularly describedand ascertained with reference to the accompanying sheet of drawings, wherein: a

I The weight box 3 of the automatic weighing scale can be coupled at willby means of a loose pin 4 with a link 5 the pin 4 pass- "weight box.'- The link of Great Britain,

box 3 is dependent from the weighbea-m of (iconnccted to the v 5 is'suspended from one of the knife-edges ofa lever 7 which is fulc'rumed by means of the link 8 on the girder framework 9, this lever 7 is connected by means'of a link 10 to a second lever 11 in order to increase the power in known manner, the second lever 11 being suspended from the girder framework 9 by means of the link 12 and being connected at the other 6 end by the rod 12 to a steelyard 14. Bus pending from the lever 11 by means of the rod 15 are a series of weights 16 by means of which the steelyard 14 is overbalanced, the weight 16 serving to counterbalance the 7 normal weight of the Weight box 3 and of the weights therein and of the lever system a hereinbefore referred to in such a manner that when a residue is being weighed the weight box is connectedto the residue system 7 by the loose pin 4 and the weight box and weights and the lever system is counterbalanced or overbalanced by the series of weights 16 in such a manner that the nose end of the steelyard 14 rises to the top of the carrier bracket 17. The steelyard is brought in equilibrium by means of a poise weight 1.8 and subordinate poise weights 19 and 20 which are traversed from the fulcrum, end of the steelyard toward the nose or free ing'th'rough a bracket end in the normal manner, the position of Y residue in the weigh hopper of the apparatus in the manner well known in connection with the weighing of the Weight of a residue. For the purpose of lifting the weight box 3 a motor-'21 is employed which is coupled to the screw gear or jack 22 which raises and lowers the yoke 23 which is coupled by means of the four rods 24 to thebottom is provided with a concave with the-convex seating 27 formed on the bracket 6 of the weight box, by this means the loose pin 4 can be readily engaged with or removed from the link 5 and the bracket When the automatic weighing scale is} functioning in its normal manner the welght the scale, the loose pin 4 being removed so that no connexion exists between the weight box and the residue weighing lever system.

' Claims 7 1. A residue weigher for use in combination with automatic scales, comprising in combination a steelyard, a poiseweight traversably mounted on saic steelyerd, a lever connected to said steelyard, a load receiver adapted for connexion to said lever, weights suspended from said lever to overhalance the steelya-rd against. the resistance of the load receiver and the weights therein, a weight recording mechanism operable in conjunction with said steelyard and poiseweight and means ior connecting and disconnecting the load receiver from the levers connected to the steelya-rd.

2. A residue weigher for use in combination with automatic scales. com risin in combination a steelyard, a poiseweight ARTHUR STUART GILBERT.
